Adjusted Peak Performance
Adjusted Peak Performance (APP) is a metric introduced by the U.S. Department of Commerce's Bureau of Industry and Security (BIS) to more accurately predict the suitability of a computing system to complex computational problems, specifically those used in simulating nuclear weapons. This is used to determine the export limitations placed on certain computer systems under the Export Administration Regulations 15 CFR. Further details can be found in the document "Practitioner's Guide To Adjusted Peak Performance". The (simplified) algorithm used to calculate APP consists of the following steps: * Determine how many 64 bit (or better) floating point operations every processor in the system can perform per clock cycle (best case). This is FPO(i). * Determine the clock frequency of every processor. This is F(i). * Choose the weighting factor for each processor: 0.9 for vector processors and 0.3 for non-vector processors. This is W(i). * Calculate the APP for the system as follows: APP ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bureau Of Industry And Security
The Bureau of Industry and Security (BIS) is an agency of the United States Department of Commerce that deals with issues involving national security and high technology. A principal goal for the bureau is helping stop the proliferation of weapons of mass destruction, while furthering the growth of United States exports. The Bureau is led by the Under Secretary of Commerce for Industry and Security. The mission of the BIS is to advance U.S. national security, foreign policy, and economic interests. BIS's activities include regulating the export of sensitive goods and dual-use technologies in an effective and efficient manner; enforcing export control, anti-boycott, and public safety laws; cooperating with and assisting other countries on export control and strategic trade issues; assisting U.S. industry to comply with international arms control agreements; monitoring the viability of the U.S. defense–industrial base; and promoting federal initiatives and public-private part ...
